↑ : Low to high transition

Notes: 1. Output level before the indicated steady state input conditions were established, provided

that CLKAB was high before LEAB went low.

2. Output level before the indicated steady state input conditions were established.

3. A to B data flow is show; B to A flow is similar but uses OEBA, LEBA, and CLKBA.
